We explore the use of the LZW and LZSS data compression methods. These methods or some versions of them are very common in use of compressing different types of data. Even though on average LZSS gives better compression results, we determine the case in which the LZW perform best and when the compression efficiency gap between the LZW algorithm and its LZSS counterpart is the largest.

introduction: to assess efficiency as a relative concept, the difference between real and expected values must be determined by comparing the productivity of economic units of industry and the efficiency in potential production conditions. as economic units, hospitals need to utilize efficiency analysis in order to make optimal use of their available resources. therefore, the present study comp...

Flow in the first two-stage of V 94.2 gas turbine is simulated numerically. In this turbine, the second stator is clocked relative to the first stator to different positions. Steady-state analysis was carried out by varying the circumferential relative position of the consecutive stator vanes to study the effects of the clocking on turbine performance. A density based compressible inviscid ...

introduction: efficiency evaluation of universities and faculties is one of the tools that help managers to identify the departments’ strengths and weakness. the main objective of the present research was to measure and compare the technical efficiency of shiraz school of medicine departments using data envelopment analysis (dea) technique. methods: this cross-sectional and retrospective study ...

Methylene blue is widely used in various industrial branches. Due to insufficient treatment, its occurrence in wastewater is frequently detected, which may result in serious environment problems to aquatic organisms. Hydroponic experiments were conducted with rice seedlings (Oryza sativa L. cv. XZX 45) exposed to methylene blue to determine the effective concentration using relative gr...
